This is a continuation-in-part of U.S. patent application Ser. No. 17/586,623, filed on Jan. 27, 2022, and titled, “Methods, Systems, Apparatuses, and Devices for Facilitating Stress Adaption in a Workstation,” which claims a priority to the U.S. provisional patent application No. 63/241,972 filed on Sep. 8, 2021, each of which are incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

Generally, the present disclosure relates to the field of chairs and seats. More specifically, the present disclosure relates to methods, systems, apparatuses, and devices for facilitating stress adaption in a workstation.

BACKGROUND OF THE INVENTION

The field of chairs and seats is technologically important to several industries, business organizations, and/or individuals.

Currently, there is a dramatic shift to telework, where there is a distinct need for efficient use of space and real estate without any reduction in capabilities or functionality compared to conventional office workstation environments. As companies normalize and standardize to the telework environment, current telework workspace solutions are using size-restricted, modularized solutions that limit their overall functionality in terms of visual real estate offered and that lack the ability to manage the telework environment acoustic noise load. To support fundamental, telework activities such as teleconferencing, these workstations typically consist of a desk, computer, monitor or monitor array, stress-adaptive chair, webcam, acoustic speaker system, and microphone.

Conventional workstations, in general, have a footprint defined in terms of the minimum desk size required to adequately perform specific job functions. In these workstations, the desk size is directly correlated to the size of the single computer monitor or monitor array that is being deployed. For knowledge-based workers who typically use multiple monitor arrays, space restrictions in telework workstations limit the amount of accessible visual real estate at their disposal and a correspondingly decrease their production efficiency.

Additionally, acoustic noise sources in the telework environment can be significantly stronger in specific frequency ranges that make them more distracting than the noise typically found in conventional office spaces, necessitating an adaptive mechanism or system to manage the noise loads.

Therefore, there is a need for improved methods, systems, apparatuses, and devices for facilitating stress adaption in a workstation that may overcome one or more of the above-mentioned problems and/or limitations.

In general, the method disclosed herein may be performed by one or more computing devices. For example, in some embodiments, the method may be performed by a server computer in communication with one or more client devices over a communication network such as, for example, the Internet. In some other embodiments, the method may be performed by one or more of at least one server computer, at least one client device, at least one network device, at least one sensor and at least one actuator.

Accordingly, in some embodiments, the storage device may be based on technologies such as, but not limited to, data compression, data backup, data redundancy, deduplication, error correction, data finger-printing, role based access control, etc.

Further, one or more steps of the method disclosed herein may be initiated, maintained, controlled and/or terminated based on a control input received from one or more devices operated by one or more users such as, for example, but not limited to, an end user, an admin, a service provider, a service consumer, an agent, a broker, or a representative thereof. Further, the user as defined herein may refer to a human, an animal, or an artificially intelligent being in any state of existence, unless stated otherwise, elsewhere in the present disclosure. Further, in some embodiments, the one or more users may be required to successfully perform authentication in order for the control input to be effective. In general, a user or the one or more users may perform authentication based on the possession of human-readable secret data (e.g., username, password, passphrase, PIN, secret question, secret answer, etc.) and/or possession of a machine-readable secret data (e.g., encryption key, decryption key, bar codes, etc.) and/or or possession of one or more embodied characteristics unique to the user (e.g., biometric variables such as, but not limited to, fingerprint, palm-print, voice characteristics, behavioral characteristics, facial features, iris pattern, heart rate variability, evoked potentials, brain waves, etc.) and/or possession of a unique device (e.g., a device with a unique physical and/or chemical and/or biological characteristic, a hardware device with a unique serial number, a network device with a unique IP/MAC address, a telephone with a unique phone number, a smartcard with an authentication token stored thereupon, etc.). Accordingly, the one or more steps of the method may include communicating (e.g., transmitting and/or receiving) with one or more sensor devices and/or one or more actuators in order to perform authentication.

Further, one or more steps of the method may be automatically initiated, maintained and/or terminated based on one or more predefined conditions. For instance, the one or more predefined conditions may be based on one or more contextual variables. In general, the one or more contextual variables may represent a condition relevant to the performance of the one or more steps of the method. The one or more contextual variables may include, for example, but are not limited to, location, time, identity of a user associated with a device (e.g., the server computer, a client device, etc.) corresponding to the performance of the one or more steps, physical state and/or physiological state and/or psychological state of the user, physical state (e.g., motion, direction of motion, orientation, speed, velocity, acceleration, trajectory, etc.) of the device corresponding to the performance of the one or more steps, and/or semantic content of data associated with the one or more users. Accordingly, the one or more steps may include communicating with one or more sensors and/or one or more actuators associated with the one or more contextual variables. For example, the one or more sensors may include, but are not limited to, a timing device (e.g., a real-time clock), a location sensor (e.g., a GPS receiver, a GLONASS receiver, an indoor location sensor, etc.), a biometric sensor (e.g., a fingerprint sensor), or a usage sensor, etc., associated with the device corresponding to performance of the or more steps.

Further, two or more steps of the one or more steps may, in some embodiments, be simultaneously performed, at least in part. Further, in some embodiments, there may be one or more time gaps between performance of any two steps of the one or more steps.

Further, in some embodiments, the one or more predefined conditions may be specified by the one or more users. Accordingly, the one or more steps may include receiving or using the communication device, the one or more predefined conditions coming from one or more and devices operated by the one or more users. Further, the one or more predefined conditions may be stored in the storage device. Alternatively, and/or additionally, in some embodiments, the one or more predefined conditions may be automatically determined, using the processing device, based on historical data corresponding to performance of the one or more steps. For example, the historical data may be collected, using the storage device, from a plurality of instances of performance of the method. Such historical data may include performance actions (e.g., initiating, maintaining, interrupting, terminating, etc.) of the one or more steps and/or the one or more contextual variables associated therewith. Further, machine learning may be performed on the historical data in order to determine the one or more predefined conditions. For instance, machine learning on the historical data may determine a correlation between one or more contextual variables and performance of the one or more steps of the method. Accordingly, the one or more predefined conditions may be generated, using the processing device, based on the correlation.

Further, one or more steps of the method may be performed at one or more spatial locations. For instance, the method may be performed by a plurality of devices interconnected through a communication network. Accordingly, in an example, one or more steps of the method may be performed by a server computer. Similarly, one or more steps of the method may be performed by a client computer. Likewise, one or more steps of the method may be performed by an intermediate entity such as, for example, a proxy server. For instance, one or more steps of the method may be performed in a distributed fashion across the plurality of devices in order to meet one or more objectives. For example, one objective may be to provide load balancing between two or more devices. Another objective may be to restrict a location of one or more of an input data, an output data and any intermediate data therebetween corresponding to one or more steps of the method. For example, in a client-server environment, sensitive data corresponding to a user may not be allowed to be transmitted to the server computer. Accordingly, one or more steps of the method operating on the sensitive data and/or a derivative thereof may be performed at the client device.

In this disclosure, ergonomic features refer to the aspects of a workstation designed for efficiency and comfort in a working environment. These features include, but are not limited to, design aspects such as seat height, seat width and depth, a distance between monitor and user, backrest lumbar support and recline positioning, swivel positioning, armrests, headrest, materials, temperature control, and mobility.

In this disclosure, stress-adaptive features refer to the aspects of a workstation designed to activate stress-relieving features such as high-frequency vibrations induced at sub 300 Hz, or reclining or changing shape depending on a desired trigger, such as input from acoustic sensors, the posture of the user, a timer, or combination of any of these triggers.

In this disclosure, the display of the concentric near-head display refers to an emissive display which can be based on any technology, such as, but not limited, to Liquid Crystal Display (“LCD”), Thin-film Transistor (“TFT”), Light Emitting Diode (“LED”), Organic Light Emitting Diode (“OLED”) arrays, Active Matrix Organic Light Emitting Diode (“AMOLED”), micro-LED, polymer light emitting diode (POLED), MOLED, spatial light modulators (SLMs), projection or angular projection arrays on flat-screen or angle-dependent diffusive screen, or any other display technology and/or mirrors and/or half mirrors and/or switchable mirrors or liquid crystal sheets arranged and assembled in such a way as to exit bundles of light with divergence apex at different depths or one depth from the core plane, or waveguide-based displays. Other sources can be generic light sources, such as one or several LEDs, backlights, or laser beams, configured for use, for example, in projection-based display systems. In some display systems, light sources can be coupled with masks or patterned elements to make the light source segmented and addressable.

A concentric near-head display is also a virtual display system, is a display system that produces images which can produce three-dimensional perception. Such images may rely on either or both monocular depth cues and vergence depth cues. Virtual images may be stereoscopic, autostereoscopic, or (auto)multi-scopic. A virtual display system may be a free-standing question, like a computer monitor or a television. It may be part of a mobile phone, tablet, headset, smart watch, or any portable device. It may be for a single user or multiple users in any application. The display content or virtual images is the set of images that the viewer sees when using the display system. In some embodiments, the virtual display system produces an eyebox whose volume is big enough to encompass both eyes of a viewer simultaneously. In this case, a pixel from a display source can be seen by both eyes. In another embodiment, the virtual display system produces a left eyebox and a right eyebox, configured for simultaneous viewing by a left and a right eye.

Virtual display systems can incorporate any hardware in displays, including liquid crystals or other polarization-dependent elements to impact properties of the display; any type of mirror or lens to redirect the light path, influence the size in any dimension, modify the focal depth, or correct for aberrations and distortions; any surface coatings, active elements; spectral or spatial filters to assist in image quality; optical cavities; or any type of element or coating to serve as a shield layer or antireflection layer to reduce unwanted, stray, or ambient light from reaching a viewer. In the embodiments disclosed herein, virtual display systems are optical virtual display systems, but virtual display systems can be of any modality, including radio-frequency or acoustic display systems, configured for consumption by a person's human auditory system. In all embodiments in this disclosure, the displays can be curved.

In some embodiments, a field evolving cavity is included as a component in the virtual display system. A “field evolving cavity” (also “FE cavity” or “FEC”) is an optical cavity in which light folds back can fold back on itself. An FEC can be a component in a virtual display system and assists in providing depth cues for three-dimensional (3D) perception for a user. In some embodiments, a depth cue is a monocular depth cue.

A “lightfield” is a mathematical model of light propagation that relies on the geometric ray approximation. Some lightfield models incorporate wave-based effects like diffraction. A lightfield display is three-dimensional display that is designed to produce 3D effects for a user using lightfield modeling. A concentric near-head or other virtual display system may be a light field display in which for any two pixels of the display at a fixed radius from the viewer, the chief ray of the first pixel's light cone intersects with that of the second pixel's light cone. In some embodiments, the concentric near-head display or virtual display system is a holographic display, which relies on the wave nature of light to produce imaging based on a wavefront of the light. A concentric near-head display produces an image that is focusable to the eye at all points.

A virtual display system, including a concentric near-head display produces image content, virtual images, of display content that trigger depth cues in a viewer, who consequently perceives the display content at a variable depth, or perceives different parts of the display content at various depths relative to each other, or perceives display content that appears at a different depth than the physical display system. In some embodiments, parallax effects are produced. In some embodiments, 3D effects are triggered stereoscopically, by sending different images to each eye. In some embodiments, 3D effects are triggered using “monocular depth” cues, wherein each eye focuses or accommodate to the appropriate focal plane or depth to see the display content clearly. Each depth at which content is located is called a virtual layer, a virtual depth, or a focal plane. The virtual depth of a virtual image may be dynamically adjustable via electric, electrooptic, or nonlinear control in the display system; a user or sensor input; or a pre-programmed routine.

The virtual images may further appear in a region displaced laterally from the physical display system, for example, to extend the field of view.

In some embodiments, the properties of interest of the display content include resolution, refresh rate, brightness, field of view, viewable zone, monocular depth or accommodation, vergence, eye box or headbox, etc.

The terms “virtual stack,” “multilayer images,” “multilayer display images,” or “overlayed images” refer to information grouped in virtual layers organized in a stacked fashion. A display system that can produce multilayer images may be called a multilayer virtual display system. For example, a multilayer virtual display system is one in which display content is shown in such a way that a viewer must accommodate his eyes to different depths to see the content. Multilayer displays comprise transparent displays in some embodiments.

Further, passive acoustic noise management refers to any passive material-based physical paneling measures that prevent or reduce the ambient acoustic noise signals that are impingent on the user's workstation environment. The passive acoustic noise reduction approaches generally consist of single-layer foam, composite multilayer foam structure, or acoustic metamaterial structure-based paneling material that is integrated into the ergonomic chair design to reduce ambient noise without any moving parts or electronics. The geometrical layout of these passive panels can be arbitrarily designed to balance the trade-off between ergonomics and acoustic noise management capabilities. The result of the noise management scheme is an isolated acoustic region surrounding the user that has significantly lower ambient noise levels.

Further, the term “acoustic foam” refers to any passive acoustic noise management material which can be based on any single or combination of, but not limited to, melamine foam, convoluted foam, polyurethane foam, and Polyester Film.

Further, the term “tactile acoustic transducer” refers to any acoustic, ultrasonic, piezoelectric, Hall effect, capacitance variation, resistance variation, or induction variation mechanism where the transducer can be used to deliver acoustic frequency vibrations for hearing through conduction, or for massaging purposes, or as stress sensors.

Furthermore, the term “acoustic metamaterial structure” refers to composite, multilayer acoustic foam structures with 3D-structured surface topologies designed to tailor the frequency-dependent reflection, transmission, and absorption properties of the effective material.

Further, “active design” or “active components” or generally the adjective “active” refers to a design or a component that can vary with an electrical signal or the acoustic signals that are perceived by the user as a function of the ambient acoustic signal spectral content and workstation specific acoustic scattering map.

Further, the term “active acoustic noise management” refers to an electroacoustic or electromechanical system that cancels the primary (unwanted) noise based on the principle of superposition; specifically, an anti-noise signal of equal amplitude and opposite phase is generated and combined with the primary noise, thus resulting in the cancellation of both noises.

Further, the term “optical microphone” refers to a microphone that uses an optical remote-pickup technology that senses the user's cheek, forehead, or chin as a membrane and that detects skin vibrations induced from the speaking process. This provides an independent and reliable reference audio signal in any environment. Unlike conventional microphones, which only pick up airborne sound energy, the optical microphone picks up skin vibration speech energy by reflecting light from the face of the speaker to the optical microphone's sensor. The wave vibration power in air is much weaker than that in body tissues, which corresponds to the voice volume in the same tissue position being higher than the background noise. This is because skin/soft tissues vibrate mainly because of sound bouncing in the inner body vocal cords and not as a response to external acoustical signals/noise. Sound waves from outside the body create minimal vibrations inside the body soft tissues (0.001 less effect than from the inner voice). Integrating optical microphones of this type into the chassis of the concentric near-head display in close proximity to the user's face provides high levels of sensitivity with a large received signal-to-noise ratio (SNR) audio signal that is remotely sensed.

Further, the terms “directional audio” and “isolated audio” refer to active acoustic systems which can be based on any technology such as but not limited to Parabolic Speakers, Flat Panel Speakers, Ultra-Sonic Speakers, or Phased Speaker Arrays for acoustic signal beam steering.

Further, an “imaging system” refers to any apparatus that acquires an image that is a matrix of information about light intensity, or, temporal, spectral, polarization or entanglement or other properties used in any application or framework, such as cellphone cameras, industrial cameras, photography or videography cameras, microscopes, telescopes, spectrometers, time-of-flight cameras, ultrafast cameras, thermal cameras, or any other type of imaging system.

Further, a “webcam” refers to any imaging system hardware that feeds or streams an image or video in real-time to or through a computer to a computer network, such as the internet. The webcam in this embodiment is designed to operate with the optical axis co-axially aligned with the user's face.

Further, a “tactile acoustic signal actuation” refers to any audio signal that is felt through touch and is heard through bone conduction or tissue conduction. Tactile acoustic transducers can produce a wide range of tactile and audible frequencies that can be coupled to surfaces and propagated to different spatial locations along the coupled surface.

Further, a “high-frequency stress transmission system” refers to the revitalizing of the lower or mid-back muscle areas via the acoustic transducer nodes embedded in the chair back and/or seat cushion that can provide traveling or spot-based tactile perturbation for soothing of tired or tense muscles in the area. Embedded heaters and/or coolers surrounding the acoustic transducer nodes provide an additional level of back muscle stress and strain reduction via targeted thermal transfer.

Further, “chair swivel mapped content control capability” refers to the ability to prescribe content displayed in the concentric near-head display as a function of the chair rotational position. In some embodiments, this is incorporated into a modularized workspace solution that is representative of the chair embodiment of the Ultra Reality display and acoustic/telecommunication hardware components such as webcam integration and chair swivel, content-specific mapping technique. Further, a movement of critical components relative to a chair's rotational swivel position is tracked.

FIG. 1 is a block diagram of an ergonomic telework workspace 100 overviewing eight different technologies that when collectively integrated into an ergonomic chair platform 101, provide a stress-adaptive telework workstation, in accordance with some embodiments. Accordingly, eight different technologies may include a near display 102, passive acoustic noise management 104, an active acoustic noise management 106, a directional and isolated audio 108, a tactile back fatigue reduction 110, a co-axial webcam 112, an optical microphone 114, and a swivel mapped content control 116.

FIG. 2 depicts an embodiment of an ergonomic workstation, where 1 is a concentric light-field near-head display, 2 and 3 are, respectively, a directional audio system and optical microphone arrays integrated into the display chassis, 4 is a robotic and telescopic monitor arm mount, 5 and 6 represent, respectively, an active noise cancellation speaker and an error canceling microphone integrated into the headrest, 7 is a seat tilt control mechanism, 8 is a tactile transducer array coupled into a mesh under tensile stress integrated into the seat back and cushion to reduce the induce high-frequency (<100 Hz) acoustic vibrations to the user body via stress transmission, 9 corresponds to an internal heater and/or cooling element locations embedded in the seat back and cushion, 10 is a co-axial webcam integrated into the display chassis. Here co-axial refers to a setting where the camera isn't directly looking at the user, but rather the camera is looking at the reflection of a user from the reflective surfaces inside the near-head display. In such a manner, the user sees a virtual image in the near-head light field display but the webcam sees directly the user's face through the reflection. 11 is a low-friction and high-load wheelbase, 12 represents a passive acoustic noise reduction paneling, 13 is a head hammock for ergonomic user head positioning purposes, and 14 is a telescopic seat height adjustment and swivel content control interface.

FIG. 3 , FIG. 4 , and FIG. 5 represent other embodiments of a complete stress-adaptive immersive station (such as the ergonomic workstation) to support telework and gaming activities, where 15 is a passive acoustical ring paneling, 16 is a vertically adjustable display immersion portal where the ring has the display inside the ring and can be moved up and down via a telescopic structure in 16, and 17 corresponds to two half-ring armrests with a keyboard embedded inside. The half rings swing to the side for the user to sit and can be closed once the user is sitting in the station for FIG. 3 . For FIG. 4 and FIG. 5 , this is just an adjustable panel that the keyboard can rest on. Further, a panel indicated by 18 represents the workstation temperature management modules with heating and cooling elements integrated beneath the panel surface.

FIG. 6 depicts the four different variants for the passive acoustic noise reduction approaches integrated into the stress-adaptive workstations described here. 19 represents a single layer acoustic melamine foam, 20 is a composite multilayer melamine foam structure, and 21 is the acoustic metamaterial structure-based paneling with surface structuring to minimize acoustic reflection and enhance absorption. The geometrical layout of these passive panels can be arbitrarily engineered to balance the trade-off between stress-adaptive and acoustic noise management capabilities. The result of the noise management scheme is an isolated acoustic region surrounding the user which has significantly lower ambient noise levels.

Further, a passive acoustic noise reduction approach generally consists of single-layer foam, composite multilayer foam structure, or acoustic metamaterial structure-based paneling material that is integrated into the ergonomic chair design to reduce ambient noise without any moving parts or electronics involved. The geometrical layout of these passive panels can be arbitrarily designed to balance the trade-off between ergonomics and acoustic noise management capabilities.

The geometrical layout of the passive acoustic paneling described in FIG. 6 is integrated into the ergonomic chair embodiments described in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 , and FIG. 5 , using either a U-shaped or V-shaped passive acoustic management embodiment, surrounding the user and positioned in the head-rest, such that it looks like a head hammock, 13, to provide maximal acoustic noise dampening while maintaining a high level of ergonomic comfort for the user.

FIG. 7 depicts the top-down perspective view of a user, 22, sitting in the stress-adaptive station 23, with the passive acoustic management embodiment geometrically laid out in a U-shape with a length of acoustic foam, 24, and angular subtense, θ, 25 between the two acoustic foam panels.

For a fixed length of acoustic foam, the amount of acoustic signal power absorption experienced by the user is a function of the angular subtense, θ, between the two acoustic foam panels for a fixed acoustic source and receiver distance.

FIG. 8 depicts the angular-dependent acoustic signal power absorption, for a signal frequency of 2 kHz, that is characteristic of the V-shaped embodiment described here, showing a stabilized operational range 26, once the angular subtense between the two foam panels exceeds 40°. Free-space signal attenuation measurements of the acoustic signal indicate or are equivalent to ˜6 dB for every doubling of the distance between the acoustic source and receiver, which, within the operational range of angular subtense, corresponds to effectively extending the physical source-to-receiver distance to a ˜5 times virtual distance to the acoustic noise source for the given amount of acoustic power absorption.

The top-down perspective view of the U-shaped chair embodiment is depicted in FIG. 9 , showing the user with head positioning defined by the headrest resembling a hammock apparatus and surrounded by the U-shaped passive acoustical management paneling. The hammock mesh is almost invisible to the sound. Therefore, while the head is surrounded by an acoustic dampening structure and is very close to acoustic surfaces, the acoustic dampening structure is not directly impacting the performance of those surfaces.

As described for the V-Shape embodiment, FIG. 10 depicts the angular dependent acoustic signal power absorption, for a signal frequency of 2 kHz, that is characteristic of the U-shaped embodiment described here, showing a stabilized operational range 26, once the angular subtense between the two foam panels exceeds 45° for a fixed length of acoustic foam, 27, that is directly behind the user and head hammock. Using the free-space signal attenuation measurement indicating ˜6 dB for every doubling of the distance between the acoustic source and receiver, within the operational range of angular subtense, there is again an effective extension of the source-to-receiver distance of ˜5 times. This means that since there is −15 dB reduction at 45° of the U-shaped side pads; this structure may attenuate the sound as if the source of the sound was almost ((15/6)×2=5) further away. For example, if a vacuum cleaner were making noise 1 meter right in front of the user sitting in this station, the noise from the vacuum cleaner to the user would sound as if the noise is 5 meters away.

An optical microphone is integrated at multiple positions within the concentric near-head light field display chassis to provide three functions: acoustic signal input for the calibration sub-system to characterize the user's acoustic environment, a teleconferencing microphone, and the error and input microphone inputs for the active noise cancellation sub-system.

The optical microphone described in this disclosure is representative of a type of microphone which uses an optical remote-pickup technology that senses the user's cheek or other membrane to detect skin vibrations induced during the speaking process. This provides an independent and reliable reference audio signal in any environment. Unlike conventional microphones, which only pick up airborne sound energy, the optical microphone picks up skin vibration speech energy by reflecting light from the cheek, forehead, or chin of the speaker to the optical microphone's sensor. There are multiple embodiments of the optical microphone that can provide this remote sensing functionality and can be described in terms of the modulation mechanism being adopted as shown in FIG. 11 . The optical microphone described within this disclosure is representative, but not limited to, the type of intensity-modulated radiative wave of optical microphone referenced in FIG. 11 .

The wave vibration power in air is much weaker than that in body tissues, which corresponds to the voice volume in the same tissue position being higher than the background noise. This is because skin/soft tissues vibrate mainly because of sound bouncing in the inner body vocal cords and not as a response to external acoustical signals/noise. Sound waves from outside the body create minimal vibrations inside the body soft tissues (0.001 fewer effects than from the inner voice). Integrating optical microphones of this type into the chassis of the concentric near-head display in close proximity to the user's face provides high levels of sensitivity with a large received signal-to-noise ratio (SNR) audio signal that is remotely sensed. FIG. 12 depicts the cross-sectional view of the optical fiber array integrated into the concentric near-head light field display chassis, where 28 represents the central transmitting optical fiber and 29 corresponds to the surrounding optical fibers in the array used for receiving of the reflected optical signals from the user. The optical fiber array is depicted in FIG. 12 is integrated into the concentric near-head display in different locations to facilitate different functionalities. FIG. 13 depicts this integration along with the transmission and receiving sub-systems that are used to launch and receive the user-modulated optical signals that are returned. FIG. 13 represents the two different optical microphone locations within the concentric near-head light field display to provide inputs for calibration, telecommunications, and active acoustic noise cancellation sub-systems. 34 depicts an optical source, 33 is an injection of light, and 32 is a sub-section that couples into the transmitting fiber of the fiber array. When the fiber-coupled source signal is modulated and reflected from the skin of the user's 38 forehead, chin, or cheek areas, the returning optical signals 37, are coupled into the receiver fibers in the fiber bundle and then optically detected, by a receiver photodiode 35 in the receiver block 39. Functionally, when a beam of light is incident on the human skin of the user, the beam of light will either be specularly reflected by the epidermis surface or refracted and transmitted into the skin. Surface specular reflection is roughly 5% and is a function of the angle of incidence. The diagram is shown in FIG. 14 describes the optical microphone functional concept, where light 40, from a light-emitting diode (LED) 41, is directed along a path 42 onto a reflective diaphragm 43, via a transmission fiber optic cable 44. The diaphragm reflects part of a light 45, into a receiver fiber optic cable 46. During a speech, the diaphragm is moved by sound signals that modulate the skin surface 47, causing the reflected light beam to be deflected 48, with the result that more or less light is coupled into the receiver fiber optic fiber element 46. At the end of the receiver fiber optic element (or cable) 46, a photodiode 49 converts the light intensity 50 variations into electrical signals. The circuitry has an audio frequency bandpass filter to filter out the lower frequency noise from the movements of the user. FIG. 15 provides a beam view perspective of the receiving optical fiber 51 relatives to a transmitting fiber 52, where the neutral 53 and deflected positions 54, depict the different amount of light coupled back through the receiver fibers and into the detector depending on the amount of membrane deflection. 55 represents the inter-fiber beam overlap area whose area is indicative of the amount of membrane deflection. Since the received light comes mostly from specular reflection of the skin, if the user moves his/her face or head or body, the directionality of the specular reflection may change notably, and the received signal may be significantly impacted. This, in some cases, can cause the SNR to go below a detectable range or induce high-frequency variations that have footprints in the lower audio range. For this reason, the optical microphone works in tandem with the embedded acoustic microphones in the system, and the final detection is done via a differential mechanism considering both the acoustic and optical inputs. The optical input, however, acts as a localized reference to help only pick up the user's voice. In some embodiments, instead of having an incoherent light sent and received through fibers; the light can be coherent laser light and receiver optics can be IR cameras capturing the interference patterns on the user's face to extract the acoustic vibrations. In such embodiments, more computational processing is needed to extract the acoustic signal, but the results may be more robust. Because of the compact size of the fiber-optic-array-based approach, the optical microphone can be distributed throughout the concentric near-head light field display chassis and stress-adaptive chair platform to provide an increased level of functionality. FIG. 16 shows this extension from a single element to an array format 1604, where combined observations using co-located electrical microphone arrays 1606 make it possible to now sample and characterize the acoustic environment that the user may be operating within under lower signal to noise conditions. Additionally, by characterizing the effective acoustic channel that the user may be operating within, active noise canceling methodologies can now be implemented to support telework teleconferencing activities.

FIG. 16 shows a system block diagram 1600 for facilitating, in accordance with some embodiments. Accordingly, the system 1600 may include an optical microphone 1602, an optical microphone array 1604, and an electrical microphone array 1606 communicatively coupled to a device 1608 configured for signal processing for dual microphone acoustic enhancement. Further, the device 1608 may be communicatively coupled to a device 1610 configured for sampling acoustic environment. Further, the device 1610 may be communicatively coupled to a device 1612 configured for performing active noise cancellation.

FIG. 17 shows a system 1700, in accordance with some embodiments. Accordingly, the system 1700 may include an input optical microphone 1702, an input electrical microphone 1704 communicatively coupled to a device 1706 configured for signal processing. Further, the input electrical microphone 1704 may be associated with an adaptive filter 1708. Further, the device 1706 may be configured for generating an output audio stream 1710.

A functional block diagram for the dual microphone acoustic enhancement block referenced from FIG. 16 is provided in FIG. 17 where the signal processing block can be implemented using a low-power audio codec processor to render adaptive algorithms such as, but not limited to, least mean square (LMS), normalized least mean square (NLMS), and blind source separation (BSS). The acoustic environment that the user may operate within is characterized using an impulse response (IR) based approach, leveraging the presence of the multiple microphones integrated into the concentric near-head light field display chassis and ergonomic stress-adaptive chair platform.

FIG. 18 provides a block diagram depiction of the process used to discern the sampled versions of the impulse response, h(n) 59, based on the sampled version of the time-dependent acoustic source, x(n) 56, and signal sampled by the user as the receiver, y(n) 58. The correlation function, R_(yx), between the signals x(t) and received by user y(t) is written as:

R _(yx)(τ)=R _(xx)(τ)*h(τ).  (1)

where R_(xx) is the auto-correlation of the signal x(t). When the autocorrelation of the input signal is proportional to the impulse of Dirac distribution, we have:

R _(xx)(τ)=σ_(x) ²δ(τ)  (2)

R _(yx)(τ)=h(τ)σ_(x) ²  (3)

where σ_(x) ² is the energy of the signal x(t). Consequently, the IR, h(τ), is obtained by a simple calculation of the correlation between the input-output signals.

In practice, the signals whose autocorrelation function approaches a Dirac distribution are the pseudo-random binary sequences (PRBSs). The signal of excitation x(n) is built starting from a periodic sequence PRBS of values 0 and 1 generated by an m-stage feedback register or a random generator. By suitably choosing the configuration of the shift register, one can generate a maximum length PRBS sequence of period L=2^(m)−1. This sequence of 0s and is 1s then converted into a set of ±V-volts rectangle pulses (rectangular function). The sampled version of the excitation signal, x(n), obtained is periodic with a period of T=L/F_(s).

The sampled output signal, y(n), is in absence of additive noise of the same period as x(n). The sampled correlation function R_(yx)(k), being of the same period as x(n) and y(n), can be calculated on an average of several periods L:

$\begin{matrix} {{R_{yx}(k)} = {\left( \frac{1}{pL} \right){\sum_{n = 1}^{pL}{{y(n)}{x\left( {n - k} \right)}}}}} & (4) \end{matrix}$

where p indicates the number of periods L. The estimate of the impulse response is obtained by the following formula:

$\begin{matrix} {\frac{R_{yx}(k)}{\sigma_{x}^{2}} = {h(n)}} & (5) \end{matrix}$

where k=1, . . . , N, and Nis the estimated number of points. The estimate of σ_(x) ² is given by:

$\begin{matrix} {\sigma_{x}^{2} = {\left( \frac{1}{pL} \right){\sum_{n = 1}^{pL}{x(n)}^{2}}}} & (6) \end{matrix}$

The parameters in this method are the length L of the sequence, the numberp of periods, and the size N of the identified IR.

With the sampled version of the impulse response, h(n), characteristic of the user's acoustic environment, and using one of the optical microphone elements that is closer to the user as an error microphone, active control of the surrounding acoustic noise levels is performed using a signal-processing methodology that reduces the effective frequency-specific sound amplitude to improve the signal-to-noise ratio (SNR) so that unwanted noise is less perceptible. Active noise canceling (ANC) is based on coherent acoustics that accurately replicates the original sound field in all forms of the active noise canceling. Further, ANC uses amplifiers and microphones inside the workstation environment, along with digital signal processing (DSP) to cancel the noise. The sound can be described as a pressure wave consisting of an amplitude and a phase. A block diagram representation of the ANC method incorporated into the workstation described here is provided in FIG. 19 . Both the input and error optical microphone outputs are fed into linear amplifiers 60, which are operated under an automatic gain control (AGC) configuration to ensure the linearity of the amplification process 61. This signal is conditioned via a digital-to-analog converter element 62, as a precursor to being processed by the DSP 65. The DSP processes the inverted version of the noise signals that are de-convolved with the error microphone signal prior to coding via an audio codec 63, to be sent to an output speaker 64.

The active noise-canceling system is incorporated within the chassis of the concentric near-head display, as well as within the ergonomic stress-adaptive chair platform. The embedded speaker device emits a wave with equal amplitude, but a phase of 180° (inverted phase, also known as anti-phase) of the original wave. The recombination process of the two waves is based on a physical principle called destructive interference. The ANC is achieved by using mixed-signal circuits or DSP, with a control algorithm to analyze the sound's waveform, to generate an amplified anti-phase wave to a transducer.

The stress-adaptive workstation described here uses audio signals that are felt through touch and are heard through bone or tissue conduction to both provide low-frequency audio and to provide tactile high-frequency massaging functionality via embedding of tactile acoustic transducer elements into the chair platform. These frequencies (50-300 Hz) are high compared to massaging vibrators that operate in sub 50 Hz and are low compared to 2 KHz audible frequencies. These tactile acoustic transducers 67, are driven by the current coming from the driving circuit 66, shown in FIG. 20 , where the array can produce a wide range of tactile and audible frequencies that can be coupled to a mesh of strings or fibers, 68, and that transmit that vibration to different spatial locations along the coupled surface, 68. In some embodiments, some of the transducers (or the tactile acoustic transducers) 67, might be used as tactile sensors to record the level and spatial profile of the stress that is given to the mesh at a certain position of the user to adaptively vibrate the areas that need relaxation or more blood flow. In some embodiments, the mesh that is coupled to the transducer array is an optical fiber which also helps in the sensing of the tensile stress between the nodes via the variations of the properties of the light passing through the fibers. In some embodiments, the mesh might be made with nylon material. The mesh is generally under tensile stress between the nodes. The mesh also helps to dampen the potential acoustic leakage of the vibrations in higher frequencies. The tactile transducers 67 don't need to be in a matrix-like array and can be distributed through the chair in such a manner to emphasize a certain ergonomic position depending on the application of the stress-adaptive station. Revitalizing of the lower and mid-back muscle areas via the acoustic transducer nodes embedded in the chair back and/or seat cushion can provide traveling or spot-based tactile perturbation for soothing tired or tense muscles in the area. Embedded heaters and/or coolers surrounding the acoustic transducer nodes provide an additional level of back muscle stress and strain reduction via targeted thermal transfer and mechanical wave transfer. The user feels as if some part of the mesh is stiffening and some parts are more flexible because of this adaptive change in the node frequencies which may overall adaptively reduce the stress. The ability to temporally sequence the activation of each independent transducer node in the array is enabled by the ability to independently activate each individual transducer element using the serial wiring 66 driving approach, where 69 is the circuit backplane insulating layer. This operation of a linear time-dependent 4×4 transducer array is provided in FIG. 21 where the strength of the tactile actuation has an intensity variation represented in grayscale. Each row of the array can be addressed as indexed by 71 for the top row, 72 for the second row, 73 for the third row, and 74 for the bottom row.

FIG. 22 illustrates a system 2200 for facilitating high-frequency transducer applications, in accordance with some embodiments. Accordingly, the system 2200 may include a high-frequency transducer array 2202 in a sensing mode, a field programmable gate array (FPGA) block 2204, a local pressure element 2206, and a high-frequency transducer array 2208 in a stimulation mode. Further, the FPGA block 2204 may include a multi-level thresholder 2210, a corrector 2212, a 32-bit controller 2214, and an interface breakout to transducer array 2216.

Resistive-based pressure sensing contact pattern areas surrounding the individual high-frequency transducer array elements provide heat map characterization of the pressure contact areas between the user and chair supports that are used to selectively target and stimulate areas of fatigue and stress. FIG. 22 depicts a block diagram representation of this process where the high-frequency transducer array is initially operated in a sensing mode where the local pressure sensor elements are calibrated using a multi-level thresholding approach to create a user-specific pressure map on the chair support areas. The 32-bit controller and DSP use the calibration pressure map to determine which individual transducer array elements need to be activated with the highest level of stimulation where stimulation strength is directly proportional to the pressure level. An example of this heat map is depicted in FIG. 23 where the pressure contour map is superimposed on the geometrical layout of the individual transducer array elements. These values are output to the interface breakout for the transducer array to operate the high-frequency transducer array in a targeted, stimulation mode.

The acoustic audio system integrated into the chassis of the concentric near-head display is composed of a phased array of speakers that are fed from a single source of audio frequency sound but each speaker transmits the sound delayed by an amount which is determined by the distance between a particular speaker and a selected region in space, so that sound from each speaker constructively adds at the selected region in space. A sufficiently large number of speakers are employed so that when a sound reaches a region in space at the same moment in time the audio volume may be increased substantially over sound in regions where there is no constructive interference. FIG. 24 provides a block diagram representation of the directional audio system integrated into the chassis of the concentric near-head light field display using an underlying beam forming mechanism to tailor the acoustic experience of the user. A standard audio input signal 75, is conditioned prior to input into a micro-controller 78, using a pre-amplifier 76, to correctly bias an analogue to digital converter (ADC) 77. The micro-controller 78 sets the path delays, and corresponding phase shift between speaker elements, before reconverting to the analogue domain using a digital to analogue converter (DAC) 79, passing through a pre-amplifier 80, to serve as the input to the output audio speaker element 81.

This technique allows audio frequency sound to be heard in only selected regions within the room or other auditory space. Multiple regions with multiple soundtracks can be created by simultaneously playing variously delayed soundtracks over each of the speakers in the array. The sound may be either audio frequency sound, subsonic sound, or ultrasonic sound. The audio frequency sound falls within the range of 15 Hz to 20 kHz, the range generally of human hearing, with subsonic frequencies being those below 15 Hz, and ultrasonic frequencies being those above 20 kHz.

The beamforming technique used here is based on the principle of phased arrays and superposition, which states that the in-phase portions of two coincident waveforms may strengthen each other in constructive interference, while the out-of-phase portions may cancel each other out in destructive interference. An array of several speakers can produce a steerable beam of sound that is markedly more directional than the beam of a single speaker.

The beamforming strategy employed in this disclosure is to focus sound by delaying each loudspeaker relative to neighbors of each loudspeaker, such that each loudspeaker compensates for the phase differences between loudspeakers and creates constructive interference in the desired direction. A delay and sum beamformer (DSB) type are leveraged here due to the simplicity of the DSB and the DSB is also commonly regarded as a baseline for beamforming performance. In the DSB, the source signal is passed to each loudspeaker, and the vector of filter weights is given by:

q(ω)=[e ^(jωτ) ¹ ,e ^(jωτ) ² , . . . ,e ^(jωτ) ^(L) ]^(T)  (7)

where τ₁, τ₂, . . . , τ_(L) are the time delays applied to the sources, calculated by

$\begin{matrix} {{{\tau_{l} = \frac{r_{\max} - r_{l}}{c}};{l = 1}},2,\ldots,L} & (8) \end{matrix}$

where r_(max)=max{r_(l)}, r_(l) is the distance between the l^(th) loudspeaker and the reference point, and c is the speed of the sound wave. For the 5-element array used in this system with no time delays assigned to any of the individual speakers, FIG. 25 provides the acoustic beamforming angular characteristics showing the beamforming lobes 82, in a polar plot representation 84, that are not optimized of the user experience 83. By assigning integer values of phase delays (π/2) to each of the speaker elements, a more user-experience-optimized acoustic environment can be defined 85. Full optimization of the filter weights for the stress-adaptive workstation areas described here results in a beamforming pattern that has acoustic nodes that spatially overlap with the end-user 86. The optimization is done in such a way as to maximize the signal to the user while minimizing the leakage of the sound outside of the chair considering the U or V-shaped dampening systems behind the user's head. In some embodiments, an ultrasound carrier might be used to create a subwavelength localized sound for higher frequencies (above 500 Hz) and the lower frequencies are conducted to the user's body via the transducer array. This may create a high level of isolation of the sound leaking from inside of the system to outside of the system. However, the frequency performance might not be as good as the phased-array approach.

FIG. 45A shows a virtual experience station with a display system and various transducers and sensors. In some embodiments, a virtual experience station is used for work or telework applications, entertainment, or health purposes. “Health purposes” or “health treatments” include relaxation techniques, stress mitigation, massage techniques, and any feature to improve a user's physical or mental well-being. A user 22 is disposed at the workstation and can be positioned by a kinematic rig. In the embodiment illustrated in FIG. 45A the kinematic rig is a chair 4500 in which user 22 is seated. However, the kinematic rig may be any suitable structure for facilitating position or supporting the body of user 22 within the virtual experience station. In some other embodiments, the kinematic rig may be a stool, a bed, a mechanical exoskeleton, another form of seating equipment, a support for standing, a support for lying down, or any other suitable equipment for positioning and supporting the body of user 22. Chair 4500 may have various mechanical or electrical adjustments to configure the position for the user. For example, the chair can produce a reclining position, a semi-reclined position, or an upright position, and it can adjust the height and angle through a swivel base.

A mechanical or robotic arm 4, which can have articulated or telescoping joints controlled by the user or the user's motion, can connect chair 4500 to display system 1. In some embodiments, robotic arm 4 is adjusted automatically. In some embodiments, display system 1 is a concentric light field virtual display system (as shown in FIG. 45A) that produces a virtual image 4502 at a position different from the position of display system 1, itself. The concentric light field virtual display system may be used to produce stereoscopic images, monocular depth images, or both. Stereoscopic and monocular depth images may include depth cues to facilitate user 22 having a better understanding of the physical and/or virtual environment. or In some embodiments, the display is a standard display system that produces 2D images or 2D video. In some embodiments, the concentric light field virtual display system is a generic virtual display system. The terms “display” and “display system” are used interchangeably throughout this disclosure.

The display system can include regions to support various transducer arrays that are used for health treatment or for audio/visual interfacing applications. In this disclosure, a “transducer array” is a set consisting of at least one element that can emit or detect a specific type of energy or signal. For example, the signal can be a mechanical wave, such as acoustic or ultrasound, or an electromagnetic wave of any frequency. In some embodiments, there may be no display system, and the virtual experience station has other various rigs to support the transducer arrays. In those embodiments that include a display system, the display system can have embedded in the bezel various transducer arrays, including a camera, camera system, or camera arrays 4504, ultrasound arrays 4505, speaker arrays, visible light arrays, or infrared (IR) or radio frequency (RF) arrays 4506. In some embodiments, the ultrasound array is configured as a high-frequency contactless massager such that the phased-array creates a focal point on the surface of the skin and moves that focal point across the surface of the skin, or it is configured as a carrier for audio signals that are directed to the user. In both cases, the ultrasound array can act as a dynamic phased array, in which the signals emitted by them are delayed relative to each other in a pre-computed way to produce localized regions of strong field intensity. The pre-computed signaling can be produced automatically, through user feedback or motion, or by any other means. In some embodiments, the ultrasound focal point can move across the skin and follow its 3D geometries, with the geometrical information fed as input from a depth camera that captures those 3D geometries. In some embodiments, multiple focal points can be programmed to emulate a sense of human touch or to provide hand massage. In some embodiments, the IR illumination on the face or skin can be modulated by the ultrasound to provide high precision movement capturing mechanisms.

A camera system 4504 comprises at least one camera and can provide a panoramic view of a user, for example, for teleconferencing. In some embodiments, a camera system comprises a plurality of cameras. The panoramic view can be used for three-dimensional reconstruction of the user. Further, the multiple cameras can capture various perspectives of the user 22, the chair 4500, or the surrounding environment for three-dimensional imaging or display applications or for processing techniques such as eye tracking, head tracking, landmark tracking, volumetric sectioning, avatar creation, background blurring, simultaneous localization and mapping (SLAM) based on the user or chair orientation or position, or eye gaze correction. Generally, the geometry of a chair, kinematic rig, person, or other object is a term that includes both the position and the orientation of each item. Cameras can also face outward, away from the specific user, for video see-through applications, in which the display system produces images that include information of the environment behind the display. For example, a camera may capture a scene behind the virtual display which is then incorporated, at least in part, into the virtual image, thereby creating a see-through effect. Similarly, cameras can capture information about the user's hands or fingers for a video see through-effect in which hand or finger tracking is used to allow the user to interact with virtual objects 4503 as part of the virtual images. The camera system can also capture information about other physical objects 3112, such as pen, paper, keyboard, or mouse to display as virtual interactive objects in virtual-reality or screen-sharing modalities. In some embodiments, the camera system is used for overlaying information on control gears of a simulation rig, configured for flight or vehicle simulation applications. In these embodiments, the virtual display is a video-see through display or is transparent or at least partially transparent (e.g., from the perspective of user 22). In some embodiments, the display system is integrated into kinematic gym gear, therapy gear, or medical gear, to help with an immersive exercising environment. In some embodiments, the ultrasonic array is used to mitigate skin humidity, sweat, or temperature or blood circulation for a better experience in exercise, therapeutic, or medical contexts.

Volume sectioning is a technique where a plurality of images of a scene are captured by a respective plurality of cameras, or by a single camera moved to different positions sequentially. Cameras are usually calibrated to minimize distortion. The different images are then compared using software to create a depth map, volume map, or a three-dimensional reconstruction of a scene. For example, two cameras may each capture an image of a scene for stereo photography. The depth information can then be used to segment objects that are located, for example, in the background of a scene, and a blurring algorithm may be used to blur those objects in the resulting image, as may be used in a shared virtual environment.

In some embodiments, the cameras of the camera system are conventional cameras. In some embodiments, they are depth cameras and capture information about depth or sense gestures and poses. They can be of any type. In this disclosure, a “depth camera,” “depth sensor,” or “RBGD camera” is an imaging device that records the distance between the camera and the distance to an object point. It can be actively illuminated or passively illuminated, and it can comprise multiple cameras to use, e.g., stereo, information. light detection and ranging (LIDAR) and time-of-flight cameras are examples of an active depth camera. A depth camera can also use optical coherence tomography sensing (i.e., autocorrelation). It can use IR illumination to extract depth from structure or shading. Depth cameras can incorporate gesture recognition or facial recognition features. Depth can also be estimated from conventional cameras or a plurality of conventional cameras through, for example, stereo imaging. The camera array or camera system can comprise any of these cameras.

The camera or camera system may capture information about the environment, the kinematic rig, or a user and incorporate that information for display on the virtual display system. In some embodiments, a plurality of users are each using a display system, the display systems each having a communications interface to communicate through a network such as, for example, the internet, a LAN network, or a daisy-chained system. The image captured by the camera of one of the display systems can then be sent to a second display system, such that the second display system can incorporate that image into its display content. This configuration would be useful for telework, teleconferencing, web conferencing, online teaching, or collaborative or multi-player gaming. In some embodiments, a communications interface is used to transfer a data packet about the image. The data packet may define the image itself, a portion of the image, properties of the image, image metadata, or any type of information about the image.

FIG. 45B is a close-up view of the display system 1 in FIG. 45A. The various transducer arrays can be embedded into portions of the display system's enclosure. They can be placed in the bezel or edges, for example. They can also be embedded in a mesh structure and added on to existing displays. IR transducers 4506 can project dynamic patterns on the user or on objects of interest and the reflected light can be used for three-dimensional facial or feature reconstruction, tracking monitoring, or security features. IR illuminators can be used for photometric stereo applications, or for light therapy applications. Ultrasound transducers 4505 or audio transducers can be used for sound production, noise cancellation, audio holography, or any combination of these applications. In the case of ultrasound transducers, the ultrasound frequency can be used as a carrier wave for audio signals. Ultrasound transducers can also be used for massage therapy to reduce eye muscle fatigue or face muscle fatigue. In some embodiments, the camera array 4504 localizes the user's ears to dynamically change the audio or ultrasound signal. In some embodiments, the IR or ultrasound transducer arrays can be used for facial treatments, such as contactless massagers, light therapy, or temperature therapy. The transducer arrays can work in concert with each other or with other arrays or elements, such as audio 2 or microphone arrays 3. In some embodiments, the information captured by the transducer arrays can be transmitted to other displays in teleconferencing applications.

FIGS. 46A through 46D illustrate various configurations of the virtual experience station, involving the transducer and camera arrays, that were discussed in FIGS. 45A and 45B. FIG. 46A depicts a user 22 in a chair 4500 that has an articulated, mechanical arm 4 connected to a display system 1. The display system can produce virtual images 4502. A camera system 4504 can capture information about the user, chair, or environment. In some embodiments, the camera is positioned to capture information about a physical scene 4507 behind the display system and then projects that information on at least one of the images of the display system to produce video see-through applications. Transducer arrays 4505, 4506 can also be embedded into the various parts of the chair.

In some embodiments, as shown in FIG. 46B, the camera system 4504 can capture information about eye gaze and eye tracking information of a user 22 and use that information as feedback for the content produced by the display system 1. For example, in some embodiments, the virtual depths of the virtual images are adjusted to different focal planes 4508, or the positions of the virtual images are shifted to accommodate a user's eye behavior. The information can be used to impact images viewed by other individuals in, for example, teleconferencing applications.

FIG. 46C illustrates an example embodiment that uses IR or near-IR (NIR) illumination. NIR illumination is the portion of the IR electromagnetic spectrum that is nearest to the visible spectrum. The IR electromagnetic spectrum also includes mid-IR and far-IR regimes. An IR or NIR transducer array 4506 can produce projection illumination onto a user 22 for dynamic lighting applications. The arrays can be coupled to the display system 1. Such an embodiment can be used for tracking the user, the chair, or the environment. In some embodiments, the IR or NIR transducer arrays can be configured as optical microphones that sense acoustic vibrations. The transducer arrays can work in concert with a camera or camera arrays 4504 to impact images produced by the display system.

FIG. 46D uses an ultrasound transducer array 4505 for localized audio. The array can be built into the display system 1. The camera system 4504 tracks the head and ears of a user 22, and the information is fed into the ultrasound array to produce localized audio or ultrasound signals at a user's ear by dynamically adjusting the relative phase delays of each of the transducer signals, so that the audio signal produced by the display system is localized near the user's ears, and that other individuals in the environment do not hear the audio signal. The system can also capture environmental noise for noise cancellation effects.

The processing pipeline for ultrasound phased array can operate as shown in the block diagram of FIG. 47A. In some embodiments, this pipeline is integrated with the block diagram of FIG. 24 . The camera system, or multicamera system 4509, records visual information about the user and sends that into a localization algorithm 4510 to reconstruct the positions of the left and right ears. The position information is sent to an algorithm that controls the phase-array output 4511. The signals produced by the transducers are then sent to environment 4512, which includes a user. Information about environment noise 4513 is detected by ultrasound, audio, or optical microphones, and the information is incorporated into audio signal 4514, which is compensated to cancel that noise. In some embodiments, the user's hearing response 4515 may be used to calibrate the system. For example, the aural transfer function of the user can be incorporated to optimize the signal produced by the transducer array.

The ultrasound transducer array can act as a beam forming mechanism for localized audio, audio holography, or acoustic fields. For example, denote the positions of the left and the right ear are located as r_(L) and r_(R), respectively. The ultrasound transducer array is configured to produce a signal f(r) that is approximately zero unless r=r_(R) or r=r_(L). The term “approximately” means to within a precision on the order of the size of the ear or ear canal. Each source transducer produces a localized wave, such as a spherical wave. The n^(th) source can produce a spherical wave A_(n)exp(i(kr_(n)+α_(n))), where A_(n) is the amplitude of the wave, k is the wavenumber (rad/m), r_(n) is the distance between the source and the point of observation, α_(n) is a phase constant, and “exp” is the exponential function. The total field is the sum of each spherical wave:

f(r)=Σ_(n=1) ^(N) A _(n) e ^(i(kr) ^(n) ^(+α) ^(n) ⁾  (9)

Processing software seeks to minimize the difference between f(r) and the ideal waveform f_(ideal)(r) that exactly replicates a desired signal:

argmin_({α}) {||f _(ideal)(r)|² −|f(x)|²|}.  (10)

Although both the amplitude and the phase offset can be modified, the phase is a more sensitive parameter and can be adjusted by introducing relative delays. If the phase differences form a geometric sequence, then the matrix corresponding to the optimization problem may be characterized as a Vandermonde matrix. Various cost functions can be included in the optimization problem. For example, prior constraints can be incorporated into the minimization.

A numerical simulation of this method, using linear phase delays is shown in FIG. 47B. In this case, a linear phase offset of a one-dimensional array of 100 transducers is introduced. The phase α_(n) is proportional to the position x_(n) of the transducer along the x-axis: α_(n)=Mx_(n) for some proportionality constant M. By increasing the proportionality constant M, the slope of the resulting plane wave changes. The tilt of the wavefront is shallowest 4516 for the smallest proportionality constant. The tilt increases to a slightly less steep slope 4517 for a bigger proportionality constant. The tilt increases further 4518 for a bigger proportionality constant. The tilt is largest 4518 for the biggest proportionality constant.

In some embodiments the resulting audio information is based on the virtual environment that a user is viewing. For example, a virtual image may be perceived as far away, based on monocular or binocular depth cues, and a sound effect due to that image will be perceived as low in volume. In contrast, a virtual image that is perceived as being closer may be associated with a sound effect is perceived as louder or more directional, i.e., as being closer to left ear than to the right ear.

If the ears are located in the far field, this tilt corresponds to a shift of the location of field maxima, as shown in FIG. 47C. The field energy is localized to regions that depend on the phase tilt. The smallest shift 4520 corresponds to the smallest phase tilt. The next shift 4521 corresponds to the next larger phase tilt. The next shift 4522 corresponds to the next phase tilt, and the largest shift 4523 corresponds to the steepest phase tilt.

Shown in FIGS. 48A through 48C are examples of applications of the camera arrays for virtual environments, such as virtual reality and teleconferencing applications, based on the virtual experience station of FIG. 45A. In FIG. 48A, each camera in the camera system 4504 captures information about a user 22 from a different perspective 4524. The information is processed for volumetric or three-dimensional reconstruction of a user. Information about facial expression, gestures, hand or eye position, and posture is recovered and used to render an avatar image 4525 of the user for virtual-reality applications with the display system 1. The camera system can perform three-dimensional reconstruction of a user or a part of a user. In some embodiments, these reconstructions are used to amplify user movements to control the virtual objects or to interact with the virtual content. In some embodiments, a predictive algorithm such as trained network for 3D hand models may be used to predict the user's intent based on smaller micro gestures.

In the embodiment shown in FIG. 48B, the display system 1 can show a virtual image 4502. The virtual image can be farther from the user or closer to the user. In some embodiments, the closer virtual images are produced using retroreflective elements, retroreflective elements, or phase conjugating elements. In some embodiments, camera system 4504 acts as a depth or gesture sensor and can allow the user 22 to interact with the virtual images. Augmented-reality annotations can also be mapped onto virtual images for a user to interact with.

Depicted in FIG. 48C is an embodiment in which the cameras in the camera system 4504 capture different perspectives 4524 and consequently capture three-dimensional information about the user's environment, such as background items 4526. The environmental information can be used for better blurring 4527 of the user's background for teleconferencing video images 4502 with the display system 1. In some embodiments, multiple users' faces can be detected, and the display system can maintain focus for those faces while blurring the mutual background.

FIGS. 49A through 49F depict various interactive features that use eye, head, or gaze tracking. The camera or camera array discussed above can track users' eyes, faces, and heads to use as eye gaze correction. In this way multiple users can interact virtually through the virtual display. Shown in FIG. 49A are two users; user A 22A is in a first room or environment 4528A, and user B 22B is in a second room or environment 4528B. These environments can be in physically distinct spaces, or they can be in different orientations in the same space. The eye gaze correction system detects where each user is looking, and the information is sent to the rendering pipelines of the display systems 1. The result is a 2D or 3D virtual environment, such as virtual office or virtual arena or field shown in FIG. 49B, in which user A 22A and user B 22B both appear to be making eye contact with each other as they look through their respective display systems 1 at virtual images of each other 4502.

In some cases, a shared virtual environment may include a shared workspace, such as a shared document or whiteboard can be used with similar features. This example is shown in FIG. 49C, which depicts the view of user A 22A from the perspective of user B from FIG. 49B. In this example embodiment, user A is sharing a workspace and interacting with the workspace's virtual images 4502, such that user A appears to be facing user B through user B's display system 1 and they can interactively write on the whiteboard or paper. In some embodiments, the camera system captures the hand and the desk space and multiplexes that information at the same location or at a desired depth layer to mimic a shared space between the calling entities.

Similarly, some embodiments are implemented with more than two users, as depicted in FIG. 49D, which illustrates the effective use of tracking, such that the virtual images produced by each user's display system make the virtual environment appear more realistic for each user. For example, the camera system and tracking methods can be used such that it appears as if user B 22B, user C 22C, and user D 22D are making eye contact with user A 22A through each of their respective display systems 1. FIG. 49E is an overhead view of this virtual environment. In some embodiments, the camera system provides a spatial localization and mapping capability such that if the user moves his/her head or swivels a chair, that movement will impact the content accordingly to further simulate presence in the virtual world.

FIG. 49F illustrates an example virtual image as seen by user A through a display system 1, in which user A sees users B 22B, C 22C, and D 22D making eye contact or facing each other in a virtual environment, configured as in FIG. 49D.

Generally a “virtual environment” is a collection of display content or virtual images, that may be able to interact with each other. The display content may have as its source camera images or computationally rendered images, such as computer graphics. The virtual environment can be a virtual reality environment, in which all the content is virtual display content; it can be an augmented or mixed reality environment, in which virtual images are super-imposed a physical environment; or in can be a conventional image content from a display panel like an LCD panel. In some embodiments, the virtual environment comprises only one virtual image. Virtual environments may be used by a single user in the kinematic rig, or they may be shared or displayed by a plurality of display systems that are in communication with each other through, for example, the internet, or any type of wired or wireless network. A “shared virtual environments” is a virtual environment that may be used for any collaborative activity, including telework applications, teleconferencing, web conferencing, online teaching, or collaborative or multi-player gaming. In a shared virtual environment, different users may view the display content from different perspectives.

As shown in FIG. 49G, in these embodiments, the camera system can use depth information about a user for depth-based remapping. Depth remapping is an example of projection remapping, or remapping. This can be used in virtual displays, or in conventional display applications. Information about a user's distance to the camera system and to the display system can be processed through a software pipeline 4529 to render a virtual image 4531 of the user that maintains the correct physical or geometric proportions of the user compared to an uncompensated or distorted image 4530. For example, projection remapping may involve calibrating a camera for distortion, using isomorphisms such as homography to map features from the physical environment to the images recorded by a camera, or implementing a neural radiance field (NeRF) for generating 3D scenes from a set of 2D images. In this way, multiple users can interact more personally and more realistically through their images 4502. Projection remapping may be used for correcting depth errors, projecting images from perspectives different the that captured by a camera, or building a composite image from a set of individual images. This application can be used for virtual reality systems or for conventional display systems. In some embodiments, artistic features or cosmetic blemishes can also be corrected.

Shown in FIGS. 50A through 50G are various configurations of the transducers described in FIGS. 45A and 45B, configured for use as health treatments, such as contactless massagers or heaters, or IR or NIR light therapy. FIG. 50A shows, from a user's perspective, the display system 1 and transducer arrays, such as ultrasound arrays 4505, that were discussed in FIG. 45A. The transducer array can alternatively be IR or NIR, UV, or visible-light transducer arrays. Here, the transducers are built into a bezel around the display system. In some embodiments, the transducers are built into a mesh 4532 that is placed over a standalone monitor, such that they therefore convert the standalone monitor into a virtual experience station embodiment that has the transducers already built into it. The transducer array that is embedded into a mesh is portable and may be used in different setups or systems. The display system 1 can be a virtual display or a conventional display.

In such embodiments, the ultrasound transducer array is modulated to direct ultrasound energy to various portions of a user's face or body. The localization of the massaging feature is on the order of the wavelength of the ultrasound wave. Ultrasound frequencies are approximately 20 kHz, and the wavelength is approximately 2 cm or 1 cm. approximately above. The ultrasound wave can penetrate to a depth different that audible acoustic waves. In some embodiments, the acoustic field is combined with a localized ultrasound field to create a holographic sound experience. This holographic acoustic field is then matched to the content being shown on the screen. For example, in a game or video when a fly passes by the character's ear and sits on his ear, the user first feels the sound coming from a far distance, then hears the localized sound next to the ear (the sound of fly's wings very close to the ear), and then feels a gentle touch on the hear from the ultrasound focal point. In another example, when an explosion happens in a game, the user first hears the explosion but then simultaneously feels an impact on his/her skin via the ultrasound phased array. In some embodiments, the holographic sound system is synchronized with the game engine to use the visual 3D geometry to emulate the needed acoustic field. In some embodiments, the acoustic field is created by a predictive algorithm that is trained using a combination of data from game engines and acoustic wave propagation physics.

FIG. 50B depicts a standalone transducer array 4505 next to a display system 1. In this case, the array is configured as a contactless face massager. The array can be connected to or rest on a desk via an articulated arm 4533, and the array position and orientation can be manipulated with a handle 4534. The transducer array can alternatively be IR or NIR, UV, or visible light arrays. The standalone transducer array can be flat or curved. Similarly, there can be a plurality of standalone transducer arrays. In FIG. 50C, for example, the display system 1 is disposed between two transducer arrays. The array can be an ultrasound array 4505 The transducer array can alternatively be IR or NIR, UV, or visible light arrays. In some embodiments, the array is located at the edges of a 2D or virtual display, or it is an accessory bar that sits below the screen.

In some embodiments, as shown in FIG. 50D there need not be a display system at all, and the transducer array can act as a contactless massager, temperature, humidity therapy device, or light treatment device as a standalone feature. It can be an ultrasound array 4505. The transducer array can alternatively be IR or NIR, UV, or visible light arrays.

FIG. 50E depicts the transducer arrays 4505 used for health treatments built into both the display system 1 and the virtual experience station itself. The arrays can also be distributed in the bezel of the display system. They can also be disposed within the chair back, headrest, arm rest, or seat of the chair. In some embodiments, it is mounted on top of the bed; the bed or chair can be in a cabin of any vehicle or airplane or in any room setting. The chair 4500, articulated or robotic arm 4, and camera array 4504 can all be configured to communicate with the transducer arrays to provide optimal signaling based on orientation and position of the user 22.

FIGS. 51A through 51E depict various configurations of the station from FIGS. 45A and 45B. As shown in FIG. 51A, the workstation can be configured such that the chair 4500 reclines to various angles. The workstation can include leg rests 4535 that are disposed at adjustable angles. Physical objects, such as a keyboard or trackpad, can be integrated into an arm as a work panel 4536 of the workstation. The workstation can also have a built-in visor 4537, which can act as either a display system for the user, or a facial treatment, or both. It can be mounted to a head-covering 4538, and the visor and head-covering can have moveable parts to optimize use. In all embodiments involving a chair, the motion and orientation of the chair can be influenced by feedback about the user's posture, health, or focus, which can be captured through sensor arrays that are electrically coupled to the workstation.

Shown in FIG. 51B is an example embodiment in which the workstation can be a standing station with a display system 1 and without a chair. In some embodiments, transducer arrays 4505 and pressure sensors are built into the floor 4539 to impact the legs or feet of the user 22. The transducer arrays can also be built into the rigs that supports the display system.

FIG. 51C depicts a chair workstation in which passive noise cancellation panels 12 or acoustic foam 24 are built into the various components of the chair 4500 for better noise cancellation effects in the audio or acoustic signal heard by a user 22. The panels can comprise, for example, melamine foam, composite multilayer melamine foam structure, acoustic metamaterial structure-based paneling, as described in FIG. 6 .

Shown in FIG. 51D is a similar embodiment, in which the sensors or transducer arrays 4505 are disposed inside the chair 4500 used by a user 22. Each set of transducers can provide a different function, or they can all provide the same function.

In all these embodiments, the transducers can be controlled by user input, local timers, remote control, or any other means.

Shown in FIG. 51E is an example tandem workstation, in which two users 22 are physically near to each other. Users A and B each have their own workstation and display system 1, but there can be a shared space 4540 in which virtual images are rendered based on the relative orientation and position of user A 22A and user B 22B. These two users can interact with other users in other environments through the tandem virtual display system.

FIG. 51F shows an example integration of the virtual display system 1 into the ceiling of the cabin for a vehicle, airplane, or a room, such that the virtual display shows a virtual image 4502 that is recessed into the depth of the ceiling 4541 and tilted at an angle that is visible to a user 22. In some embodiments, the user sits in a chair 4500. The display system has a mirrored or half-mirrored segment 4543 with a hidden camera 4504 behind the mirrored or half-mirrored surface 4542, such that the user 22 sees virtual objects 4503 at the same depth of the reflection 4542 of his/her hand and can interact with those virtual objects in the depth of the mirror without having to touch the screen. In this way, the display system, mirrored or half-mirrored surface, and camera together form an interactive virtual mirror display. In some embodiments, the hidden camera is a depth camera feeding depth information to a half-mirrored section of the virtual screen. In some embodiments, passive noise cancellation panels 12 or acoustic foam 24 are built into the various components. In some embodiments are integrated other transducer arrays, such as ultrasound, IR, RF, visible-light, UV, microphone, or camera arrays.

FIG. 51G shows an example integration of a similar system as in FIG. 51F, configured for use with a bed 4544. The display system is connected by a hinge 4545 hinged to a wall or a flat surface behind the head of the user, where the mount base 4546 goes under the mattress to mechanically support the weight of the display. The hinge lets the display system fold up against or align with the wall or flat surface. In this embodiment, like the embodiment in FIG. 51F, along with a tilted and recessed virtual image 4502, the user sees his/her own hands' reflections 4543 in the half-mirrored section and can interact with the virtual content or virtual objects 4503 without having to hold up the hand. The user can rest a hand on his/her body because the depth of the virtual images matches the depth of the reflection of the hand. The user can interact with the virtual objects naturally in the half-mirrored section while seeing the content hovering behind the aperture of the virtual display. The display then can fold back to be vertically integrated into the wall. In some embodiments, passive noise cancellation panels 12 or acoustic foam 24 are built into the various components. In some embodiments are integrated other transducer arrays, such as ultrasound, IR, RF, visible-light, UV, microphone, or camera arrays.

In all bed and chair embodiments in FIGS. 51A through 51G, the chair can have transducer arrays and other interfaces to reduce stress, improve immersion, or provide medical use cases.
